Abstract

An electronic sensing system has a transceiver with input and output pads, an excitation circuit connected to the output pad, and a detection circuit connected to the input pad. An electrically-conductive sensor patch has an electrical state that changes with exposure to a corresponding environmental factor. The detection circuit detects an electrical state of the input electrical-connection pad in response to the excitation signal and the electrical state of the input pad. Several electrically-conductive sensor patches are distributed over the substrate so that they are exposed to an external environmental factor substantially contemporaneously, each having a conductance susceptible to a respective environmental factor. The output pad is electrically connected to the input pad through the sensor patches in series, so that the detection circuit detects an electrical state of the input pad in response to the excitation signal and the respective conductances of the sensor patches.
